[mythtv-users] Yadif Jerky

[Mitch Gore]

Hi,

I have been messing with my video profiles recently to improve my picture
quality.

I choose High Quality. When playing ATSC 1080i I can see im using Yadif

The picture is really jerky.  Although running mythfrontend in the terminal
I dont see any streaming errors.

Some info on my machine:

Is my machine really not fast enough to use Yadif?  Or is there some
configuration I can change to improve things?

Thanks,
Mitchell
